Couple of engine leaks

[Bydant]

So I have a couple of leaks around the engine (2011 147 TSI), the most disconcerting is the one originates from somewhere under the intake manifold. the other from what appears to be the cam advance / top timing cover at the section that the dipstick holder is attached.

The first leak from under the intake manifold s the worst and seems to have appeared over the last week or so.

Can anybody shed light on the causes and suggested remedies?

Also, the best resource for engine disassemble / assembly details?

I had a similar leak which was fixed under warranty. Sorry not a lot more details other than a number of seals were replaced.

So after looking around further, it looks like a coolant leak (black sludge is water soluble). So is that a water pump replacement or are there seals? The car has done 80,000kms.

Also Ticking time bomb or still driveable, given that I will repair in the next 2 weeks?

Unfortunately I am 10 months out of warranty. Its all DIY for me!

Replace the magnet and bearing frame seal for the cam solenoid leak. Will also have to change over the electrical connector. Won't take you more than 30 minutes.

The other leak I can't really comment on, pictures aren't so good. Although the locations in the pictures are right where the waterpump leaks, except for the shot of the mechatronics cover. Nothing else in that area really does leak however, so it would be a safe bet.

Why does the electrical connector need to be replaced?

That is the oil sump directly under the water pump. So is that a full unit replace or a seal / gasket replace?

Are there other consumable parts that are required when removing the intake to fix the pump?

[Snail Style]

They changed the connector on the new cam valve/magnet. There is just a plastic block off cover under the waterpump, never seen them leak.

Intake doesn't need to be removed to do the waterpump. Only the rad hoses, aux water pump and i take the throttle body out also.

Waterpump requires the pump itself and 3 seals to be repaired if it is leaking.

Ordered the parts today.

water pump, oil cooler o rings, seal for the camshaft magnet, intake seal, hall sensor seal (got a few as they are prone to leaking apparently), injector seals (may need them in the future) and turbo return hose seals. All up looks like its about $500.

The only reason I am getting the intake seal and the injector seals is that I want to check the carbon build up on the valves, clean the throttle body and give the intake runners a clean.

Might have to run diagnostics to recalibrate the throttle when done.


Thanks for the help!

Was was the labour involved in getting this leak fixed?

I have the same leak. Is it a big job?

[Bydant]

If you are talking about the oil leak on the magnet, I haven't sorted that on out yet.

The problem is with the way that the magnet unit is put together, and it relies on the press fit of the magnet to the fixing plate.

I haven't bought a new magnet yet, so have not fixed the leak, but it is a quick job to remove and refit, if you have a torque wrench that will fit in the space.

Apparently it also requires a new electrical connector as well, so keep that in mind when doing the job.

Magnet: 06L109259A ~ $210
Connector: 4H097302A $10

Those are VW Australia prices, but I tend to use https://www.subarugenuineparts.com/catalogs.html to get my VW parts. Works out about 50% cheaper in most cases.
